In the TV series House M.D., what is Dr. House’s first name?

Dr. House’s first name in House M.D. is Gregory.

The character’s full name is Gregory House, and he is the central diagnostic physician in the series. Most characters usually call him “House,” while patients and colleagues sometimes use the more formal “Dr. House.” His first name appears in character records, dialogue, and storylines involving his family and professional history.

House’s name is partly associated with his abrasive, highly individual style. He often ignores social conventions, challenges hospital administrators, and prioritizes difficult medical puzzles. The surname also makes the title House M.D. work as both a character reference and a medical setting signal.

The character is portrayed by Hugh Laurie. Although the show is an American medical drama, Laurie is British, and his performance helped make Gregory House one of television’s best-known fictional diagnosticians. The character was loosely inspired by Sherlock Holmes, especially in his deductive reasoning and unusual personality.
